Edfa thiab EYDFA yog dab tsi?

Edfa yog cov cuab yeej siv kho tshiab uas tsis muaj cov cim hluav taws xob muaj zog ntawm cov khoom siv kho kho kho kho tshiab nrog cov khoom siv roj ntsha

Cov Nta Tseem Ceeb:Tsawg lub suab, siab nce, dav bandwidth

Chaw nres nkoj:

1. Cov teeb liab tawm tswv yim chaw nres nkoj (hauv): Txuas lub zog 1550nm lub teeb liab uas yuav tsum tau ua kom nrov dua (xws li lub teeb liab tom qab kho qhov muag tau ploj, lossis lub teeb liab uas tsis muaj zog ua ntej tus txais). Lub zog tawm tswv yim yog feem ntau -30 rau -10 dbm thiab yuav tsum sib phim hom kev siv roj ntawm lub fiber ntau (xws li smf-28).

2 Cov zis hluav taws xob yog feem ntau ntawm 0 txog 20dbm (milliwaternts qib tsim (kom tsis txhob muaj teeb meem qis (kom tsis txhob muaj teeb liab rov qab cuam tshuam kev cuam tshuam (kom tsis txhob muaj teeb liab

3. Cov chaw nres nkoj twj tso kua mis: txuas rau lub twj tso kua mis los muab lub zog ua kom zoo siab rau lub erbium ions (tseem ceeb zog lub zog tso tawm). Lub ntsiab hluav taws xob wavelength: 980nm (suab nrov tsawg) lossis 1480nm (siab siab); Tso fais fab 100 ~ 500mw.

4. Saib xyuas chaw nres nkoj (Mon): Kev rho tawm 1% ~ 5% ntawm cov zis tawm rau tiag tiag ntawm lub hwj chim lub zog thiab wavelength ruaj khov (rau kev ua haujlwm siv). Cov zis ua kom muaj zog yog qhov qis dua qis dua lub teeb liab tseem ceeb (feem ntau-5 ~ -10dbm), uas tsis cuam tshuam rau kev sib kis ntawm lub teeb liab tseem ceeb.

Kev Ua Haujlwm Lub hauv paus:

1. Tso cov tsoos tsho (kev txhaj tshuaj kom lub zog

2. Cov pej xeem inversion (mob rau amplification) lub siab- lub neej muaj zog thiab sai sai} - Lub sij hawm rov qab ua haujlwm); Thaum tus naj npawb ntawm cov lus er³ nyob rau hauv lub xeev metastable nyob rau hauv lub xeev me ntsis tshaj li ntawd ntawm cov pej thuam hauv av, ib tug neeg inversion "tshwm sim (ib qho kev mob siab rau kev kho qhov muag).

3. Cov Npe Hluav Taws Xob (txhawb nqa cov teeb tsa) Lub teeb pom kev uas yuav tsum tau nkag los rau hauv lub pob txhatse-}}}} chaw nres nkoj. " Lub photon lub zog ntawm lub teeb liab teeb zoo sib xws los ntawm lub xeev er³ning rov qab mus rau zaus nrawm, theem, thiab duab kos rau lub teeb liab; Cov phwv tshiab no superconductionively sib txuas nrog thawj lub teeb liab teeb, tiav "lub zog tshaj tawm" ntawm lub teeb liab, uas yog qhov kawg tso tawm los ntawm "Outpute chaw nres nkoj."

Cov Ntawv Thov:

1. Ntev - deb ntawm cov khoom sib txuas lus fiber ntau dua tshiab

2

3. Hauv Catv (Cable TV) cov tshuab, lub suab paj nruag Ambeviseng rau ntau pua mais kev ua haujlwm, zam kev ua kom zoo vim kev ua raws li.

4. Optical Fiberening systems, blofifififififify tsis muaj optical tsom kwm ntawm kev sib txuas thiab roj thiab roj thiab ntau dua 100 km).

Doping ob lub erbium ions thiab ytterbium ions hauv lub teeb meem kho qhov muag hluav taws xob thiab hloov kho lub zog hluav taws xob thiab hluav taws xob siab ntawm cov hluav taws xob ntawm Edfa.

Cov Nta Tseem Ceeb:Piv rau edfa, nws tau siab dua cov cua nqus kev ua tau zoo, muaj zog zog ua siab ntev, thiab siab dua cov zis zog.

Chaw nres nkoj:

1. Cov teeb liab tawm tswv yim chaw nres nkoj (hauv): Txuas rau 1550nm teeb liab liab (-20 rau 0dbm) thiab muaj zog tiv thaiv (kom tsis txhob kub hnyiab).

2

3. Cov twj nres tsheb twj tso kua mis: Ntau lub twj tso kua mis tuaj yeem txhaj rau kev sib xyaw ua ke kom nce tag nrho cov twj tso kua mis (cov tseem ceeb ntawm cov zog tso zis ntau). Cov twj tso kua mis tseem ceeb wavelengths: 808nm (tus nqi qis) lossis 915nm (high efficiency); Ib lub twj tso kua mis ntawm 5 txog 20W, tag nrho cov zog ntawm ntau lub twj muaj peev xwm ncav cuag ntau dua 50W.

4. Saib xyuas / Tswj chaw nres nkoj: ① Cov neeg pom muaj zog thiab kub (kom tsis txhob muaj kev kub siab ntxiv); ② Kev Tswj Xyuas Sab Nraud rau kev kho cov twj tso kua mis / nce. Kev soj ntsuam chaw nres nkoj extracts 0.1% rau 1% ntawm lub teeb liab (kom tsis txhob cuam tshuam lub zog hluav taws xob siab); Chaw Tswj Xyuas Chaw nres nkoj txhawb RS485 / EURNET raws tu qauv.

Kev Ua Haujlwm Lub hauv paus:

1. Pump Excitation (Ytterbium Ion Preference) Multi-pump lasers inject pump light at 808nm/915nm through the "pump port". Tus txiv neej ytterbium ions (yb³) nyob rau hauv cov neeg muaj fiber ntau ntxiv uas nyiam nqus lub zog, kev hloov pauv hauv av hauv av (²) rau lub xeev zoo siab (²f₅ / ₂).

2. Lub zog hloov chaw (ytterbium rau erbium) tus pog ytterbium ions tsis ncaj qha emit photons; Hloov chaw, lawv hloov pauv hluav taws xob rau lub zog ua ke kom nyob ib sab ntawm lub xeev erbium (44₁₅ radiative hluav taws xob (44₁₅ / ₂) rau lub xeev metastable (44₁₃ / ₂). Cov kauj ruam no tseem ceeb ntawm cov khoom siv hluav taws xob qis ntawm cov twj tso kua mis lub teeb hauv Edfa thiab zam lub zog khib nyiab tshwm sim los ntawm kev ua kom siab ntawm erbium ions.

3. Cov Npe Hluav Taws Xob (Eth Stimulated Emission) Zoo ib yam li Edgium: Kev tso tawm ntau yam kev hloov pauv, tso tawm ntau zaus kom ua tiav cov teeb liab kev ua kom sov. Vim tias lub zog hloov hluav taws xob muaj zog los ntawm ytterbium ions, nws tuaj yeem txhawb nqa hluav taws xob ntau dua cov zis (watt}} {{5} {5} {qib).

Cov Ntawv Thov:

1. High {{{- Lub Zog Hluav Taws Xob Hluav Taws Xob thiab Kev Siv Hluav Taws Xob Ntau Tshaj Tawm

2. Muaj {{{{{{}}}} Tus tub ntxhais ua cov khoom siv hlau (stainless hlau), xws li kev kho kom ntev (xws li tsheb tsim khoom, aerospace).

3. Kev kho mob laser, cov txiaj ntsig wat-}}} Cov plaub hau kev phais mob (xws li cov plaub hau kev hloov kho)

4. Qhov chaw sib txuas lus, qhov chaw muag khoom qhov chaw ua haujlwm hauv lub teb chaws muaj zog, xws li laser ntaub ntawv sib txuas lus los ntawm cov ntaub ntawv laser ntawm beidou satellites.

5. Hauv kev tshawb fawb ntawm kev tshawb fawb, siv rau Laser Spectral kev tshawb xyuas, xws li laser tsav qhov chaw rau inertial contrinement fusion (icf).
